Description

Tuner convenient to install

Technical Field

The utility model relates to a articles for daily use technical field especially relates to a tuner convenient to installation.

Background

A tuner: is a device used by a television set to receive high frequency signals and demodulate video information, and is also the first part of the public channel. The present tuner used by tv is generally divided into digital tuner (abbreviated as digital tuner) and analog tuner (abbreviated as analog tuner). The system is a tuning and high-frequency signal amplifier for receiving television signals and a satellite television decoder.

The tuner is used for amplifying weak video signals and processing image deformation and interference caused by unstable transmission. The video processing chip determines the resolution of the image, and the tuner determines the stability of the image. However, the tuner itself is very susceptible to electromagnetic interference, so the built-in tv card usually wraps a metal layer outside the tuner to shield the electromagnetic interference.

The digital tuner is used for receiving high-frequency signals of a digital television, performing channel selection, high-frequency signal amplification and frequency conversion processing, and some tuners also have functions of intermediate-frequency signal amplification and high-frequency digital signal demodulation, wherein after the high-frequency digital signals are demodulated, the output digital signals are TS (transport stream) streams, and the TS streams are: also called transport stream, it is a digital signal transport stream in "frames" unit, each frame of digital signal contains synchronization header, data, end, etc. for MPEG2 digital signal, each frame of signal is composed of 188 bytes long binary signal packets, the content of which contains one or more programs. Here the concept of "frame" is very similar to a frame in a television picture but the content is different, and a frame of MPEG2 digital signal corresponds to a frame of picture, which corresponds to only a few pixels in a picture content. According to the modulation mode of receiving high-frequency digital signals, the digital high-frequency tuner also comprises QPSK modulation, 8PSK modulation and QAM modulation high-frequency tuner. QPSK and 8PSK modulation tuner is mainly used for satellite television signal reception; the QAM modulation high frequency head is mainly used for receiving cable television signals. The analog tuner is used for receiving the high-frequency signal of the analog television and carrying out channel selection, high-frequency signal amplification and frequency conversion processing, and the analog tuner does not have the functions of intermediate-frequency signal amplification and high-frequency signal demodulation generally, so that an intermediate-frequency amplifier and a high-frequency signal demodulator are additionally required for the analog television.

Generally, circuits for receiving, amplifying, demodulating and the like of analog high-frequency signals need to be strictly adjusted to meet the requirements of the whole machine, so that the functions of receiving, amplifying, demodulating and the like of the high-frequency signals are difficult to be completely completed by a high-frequency tuner, the main task of the analog high-frequency tuner is to select a frequency channel, the other task is to reduce the frequency, the received high-frequency signals are reduced to be above a fixed frequency, the fixed frequency signals are intermediate frequency signals, and the frequency of the fixed frequency signals is generally 38 MHz. The intermediate frequency signal is a high frequency signal for video, and it needs to be further amplified before demodulation and various processing (such as synchronous separation, bright and color signal separation, etc.), and the task of the intermediate frequency amplifying circuit is mainly to amplify the intermediate frequency signal and demodulate the audio and video signals. In addition, if amplification is also very specific to video signal demodulation, synchronous detection is generally used, and envelope distortion is very small. The intermediate frequency signal is demodulated to output a video signal and an audio signal, i.e., an AV signal, which is further processed (decoded) into R, G, B (red, green, and blue) tricolor signals. There are few, most analog, televisions that can receive digital signals (e.g., satellite television).
